Chapter 615: Morbid Crisis (IV)
Thinking of the props to cover up the smell, the next task for the two was to determine which cleaning company the Central Bank hired and what cleaning agent the cleaning company used.
The cleaning company was easy to judge. Their blue uniforms said it all. Lex operated the keyboard next to them and said, "Luther Manor had hired this company before. Their full name is Metropolitan Snow Mountain Cleaning Co., Ltd., which is also the largest cleaning company in Metropolitan, with more than 1,800 employees..."
"Here, this is their information. I hacked into their internal database and retrieved their recent business information. According to this information, the Central Bank booked a cleaning service for the glass curtain wall on March 18."
Bruce came to the screen and looked at the information displayed on it. The order information on it showed that the Metropolitan Central Bank had booked a cleaning service for the glass curtain wall. There were 50 employees involved in this service, including 43 cleaners, all men, excluding technicians and drivers.
The information showed that they sent a total of three vehicles, each with four large tool boxes, one of which contained all the cleaning agents, but the specific brand was not displayed.
After checking their purchase order, Lex continued to operate on the computer screen. He said: "The raw materials of the Palo brand cleaning agent are marked with a blue bear head, so it is also called the Blue Bear Cleaner. Xueshan Company has been using this cleaning agent for more than ten years."
"The cleaning agent specifically used to clean the glass curtain wall does not have a finished product. You need to purchase the cleaning agent raw materials and mix them yourself. I am looking for the specific information they purchased..."
After operating the computer again, Lex said: "Their formula is confidential, but the approximate chemical formula can be found. Judging from the ingredients, there must be an odor, but can it be covered up? I smell blood, and I'm not sure. "
Bruce glanced at the ingredients on the screen, and he said: "These ingredients mixed together will definitely smell. The Wayne family owns many chemical factories, and some of them produce detergent raw materials, but if the bottle is well sealed, the smell will not be revealed. "
"This is easy to solve. Just make some accidents, let a few bottles break, and then let the smell remain on the truck, or simply sprinkle detergent on fabrics such as mops or rags in advance, the smell will remain for a long time, put it in the same truck, and it can also be covered when it is transported. "Lex said.
Bruce glanced at him, his eyes were probably "Why are you so skilled?", Lex responded without any fear, meaning "same here".
The two watched all the surveillance videos again and began to analyze which toolbox was the toolbox for hiding the body. Once the toolbox was found, the person who carried the toolbox could be locked, and then he was very likely to be the murderer.
There are eight large toolboxes in total, two of which are not sealed and contain relatively few things. There are pictures of the items in the boxes, so they can be ruled out. The remaining six toolboxes are completely sealed and look exactly the same.
The surveillance in the central bank is missing a lot of places. Half of the important first-floor lobby is a blind spot. What's more terrible is that there is no surveillance at the elevator on the first floor. In other words, after these boxes were moved to the elevator, it is impossible to tell which box got on which elevator and where it went.
Bruce and Lex discussed for 20 minutes, repeatedly measuring the people, boxes and routes, and finally they could only lock the suspicious boxes within the range of three, and these three boxes were all not filmed in the scene of transportation or use.
Finally, when watching the surveillance pictures frame by frame, they finally found that a certain picture of one box was different from the others.
The surveillance picture shows that a cleaner was pushing one of the boxes and was suddenly stopped by a woman when he was walking through a corridor.
The surveillance footage only captured the feet of the two people and the bottom of the box, but not their faces or their conversation. There was nothing unusual about the cleaner and the box, but the shoes on the woman's feet were different from those of the bank employees.
Lex found a promotional video of the Central Bank on the Internet. All the female employees here were dressed the same. They all wore professional suits and even the same shoes. The shoes worn by the woman in the picture were not the gray round-toed high heels worn by bank employees, but black pointed high heels.
Based on the style of the shoes, Lex found the brand of the shoes. It was Prada's new product of the season. The price was very high and needed to be booked in advance. In other words, ordinary female bank employees could not afford this pair of shoes. Those who could wear this pair of shoes must be rich or noble.
Following this clue, Bruce and Lex deduced that the woman should not be a bank employee, but a boss who came to handle business.
So, Lex started to check the bank's large-scale business of the day, and then he found that since the end of February, the central bank has been following up on a large transaction. The two parties to the transaction were Pairo Chemical Raw Materials Production Co., Ltd. and Snow Mountain Cleaning Co., Ltd., among which Pairo Company had a large loan approved by the president himself.
The cold light of the computer shone on Lex's face, turning the red hair on his forehead into a weird purple. After he looked at it intently for a long time, he stood up and looked at Bruce and said, "Now there is good news and bad news."
"The bad news first." Bruce interrupted Lex and said.
"The good news is that I found out the identity of this woman. She is the boss of the Palo Company. She came to the bank building today to discuss business with the bank president."
"But the president has been killed, so her business should not have been negotiated." Bruce said: "She should have seen one of the tool boxes, and their conversation lasted more than 30 seconds. If there was something wrong with the tool box, she should have noticed it. Can we contact her now?"
"That's the bad news." Lex turned around and looked at the screen and said: "She is the second victim."
Lex turned around and pressed a button, and a picture appeared directly on the screen. It was a middle-aged woman with light makeup, but Bruce and Lex had seen another look of her on the news, that is, her chest and abdomen were cut open, her ears were cut off, and then a signal receiver was plugged into her ears.
Bruce suddenly paused, and then said: "The murderer is guiding our sight."
He turned around. He looked at Lex, and both saw the same information in each other's eyes.
"Professor Schiller said..." Lex began to pace in place, he said: "The real serial killer will deliberately leave all kinds of clues to guide the investigators' attention and let the investigators pay attention to what he wants the investigators to pay attention to..."
"What does he want us to pay attention to?" Bruce asked a question, but he was not asking, because later. He asked and answered himself: "The first victim is the president of the bank, the second victim is the boss of the Palo Company, and there is a business negotiation between the two of them..."
"What is the deal between the bank, Palo Company, and Snow Mountain Company? Why did the murderer kill the leaders of both parties?" Lex narrowed his eyes and asked: "What is behind the murderer's guidance of our attention to this deal? So, should we pay attention to this part?"
"Professor Schiller also said that the murderer's guidance of the investigator's attention is not without purpose. They often want to reveal some facts by letting the investigators discover his motives. It may be some grievances, or it may just be his tragic experience and hatred, or simply the murderer's understanding of something." Bruce said while recalling.
"In other words, there may be other hidden secrets behind this deal?" Lex stopped pacing and stood there to think.
"Generally speaking, ordinary murderers will use all kinds of methods to erase clues and try their best to prevent investigators from discovering themselves."
"But serial killers are just the opposite. They will deliberately leave all kinds of clues to guide investigators' attention. Therefore, when investigating serial killers, following his guidance is not necessarily a bad thing. It may allow us to discover his motive for killing." Bruce said, and then he turned around and walked towards the door, saying as he walked:
"I'm going to investigate the bank, Snow Mountain Company and Palo Company to see if there are any problems in these three places, and you..." Bruce paused at the door and said, "You continue to contact the police and get the information of the second case. In addition, keep an eye on the boss of Snow Mountain Company. He may become the third victim..."
After speaking, Bruce left, and Lex called up a new interface, which showed the results of the police investigation. The only useful information in it was the timeline provided by the witnesses.
The last person who witnessed the bank president's appearance was a guard near the villa where he lived.
At 6 p.m. on April 2, the bank president drove his car back to his residence. His family was not in the city, so he lived alone and never came out again. On April 3, the body appeared on the street in front of the bank gate.
There were no cameras near the street where the villa was located, and the patrol guards did not provide any clues of suspicious people. Even no one in the two nearby blocks found any suspicious conditions. Therefore, this clue was broken, so Bruce and Lex focused on what happened in the bank building.
Soon, Lex got the timeline information about the second victim from the police, but there was a very strange place in it.
The police data showed that the last witness who saw the female boss said that he had seen her near the president's office on the 16th floor at 1 p.m., and no one saw her again after that.
However, the surveillance footage that Lex and Bruce had just seen showed that at 1:10 pm, the female boss stopped the cleaner in a corridor.
In other words, the cleaner who was pushing the box was the last witness, and none of the cleaners' testimonies mentioned this.
In other words, Bruce and Lex's inference is likely correct. The murderer mixed in with the cleaners and killed the second victim on the spot after dumping the body of the first victim.
Lex lowered his head and looked at the data transmitted by the police. It showed that the second victim's body was found on the street in front of the Palo Company Building.
